Abstract:
Dust storms originate from the desert regions of the northern China and Mongolia and are common every year in China during spring season. Depending upon the meteorological conditions, dust reaches to Beijing and beyond to Bohai sea. Due to dust transport, the air quality, atmospheric, meteorological and ocean parameters are affected. Using multi-sensor satellite data, it is now possible to monitor the changes on land, atmosphere, meteorological and ocean color parameters and to study the impact of dust transported from source region along the track of dust. We have used multi-sensor satellite data for the dust season during 2003-2014 to study the changes in atmospheric and meteorological parameters and corresponding ocean color parameters. Our detailed analysis show an enhancement of chlorophyll concentrations in Bohai sea associated with dust storms. The enhancement in chlorophyll concentrations occur few days after the dust reaches over the Bohai sea and its surroundings. The enhancement in Chlorophyll concentrations depends on the physical and meteorological conditions of Bohai sea.
